Y. Cranford, county of U nien-, a

To aZZ whom it may/c c W'HEINS a citija resident of nd State of New is aspecification.

My invent nrelates to mechanical musical tomechanical players forStruments and to the perfoets used in connection therewhen themusic-sheet is in or out of exact almement with' the tracker ducts andfor readily readjusting it to proper alineinent.

In the drawmgs,`Figure` 1 representsv in front v elevation so much of amechanical Inusical instrument or mechamcalmstrumentplayeras isnecessaryto show the invention. ig. 2 is a transverse vertical section throughvtho 151132 2 of F 1 lool-ing to tho loft. 'o

` 1 des' nates a tracker-board provided with the usull duct-aertures11,-one at the middie ofthelboar being omitted, leaving a -spaceapproximately equalto the width of' one a erture between them.

2 esignates a take-upv roll rotated by a shaft 21, which is turned bysuitable and well-known means.- (Not shown.) A

3 designates a music-roll which carries the ordinary music-'sheet 31,provided with the usual note-perforations 32 for cooperating ducingdevices. In addition to the perforations 32 the sheet 31 is provided-with an lthe ordinary means (not s own) for rotating Specification ofLetters Patent. ipiiottio mea 'Juno 24,1905. serai No. 266,732.

which may detachably engage with the shaft It will beseen that theoperator by turning f tho key o3, in-oahor dirootion-moy, throughthe'worm'O and lug 57, turn the rockshaft 53,"which in turn acts throughthe lugs 55,

engaginglin the grooves 51 of the collars 5, to adjust t e'shafts 21.and 34 simultaneously "and equally in either direction longitudinallyof the tracker-board 1, or, in other words, laterally of the path ofmotion of the music sheet 31,y which travels over the tracker. It will be observed that this lateral movement of the sheet may be produced atany time, whether or not the sheet is in operation. v

kFig.1 shows the indicator-arm' 7, which forms an important feature ofthe invention;

It is shown as ivotall mounted on the tracker 1 althoug it is o viousthat it might be mounted on any other convenient part of the instrumentwhich is in fixed relation to the tracker-board. When in its operativeposition, its: ointed end 71 exactly corresponds with t e uide-line 30yon the sheet 31, providin that t e-sheet is in roper adjustment wit thetracker, in whic case the perevice the driving-shafts 21 and 34artition-walls 43 and' 4 4. vOnj each of the s afts 21 and 34 is mounteda col- I' *the shaft whenitis -desired to rewind the IOO i" yfrufflttedguide-line will accurately overl theimperforate space betweenthe tvvnseries of ducts 11 in the tracker. By means of this indicator theoperator is enabled to immediately note lthe slightest variation ofthemu sic-sheet fromjits A true lateral'position with- `relation to thetracker and by means of the,

ke 63 to instantly correct the same. v

t is of course understood that'while the instrument is being played theindicator' 7-is stationary, so that its point'71 always occupies thesame position relative to the tracker For convenience,`however, theindicator may be-pivoted, asm Fig'. 1, so that 'it can be swung up' awayfrom' the sheet for convenience in placing' the music-roll 3 in position'orinremodving theV same from the instru` ment.

It is ofcourse obvious'that other vdevices than' that shownmay beused'to secure the relative movement of the music-sheet lor itssupportingsrolls and the tracker-board to.

provide'the required lateral adjustment.

It isclear that by the word f linefor the phrase 'gudeylinefJas usedhereinrI intendv .to include as .equivalents a-broken line either ofperforatio'ns or imprinted -upon the sheet in the fornrof-a series ofmarks -made at inter- 1.` In a vmechanical musical instrument, in.combination, a tracker, a music-sheet, means for supporting and movingthe sheet over said tracker, means'for giving relative adjustmentbetween the v'music-sheet and said tracker `laterally ofthe path ofmovement of themu-4 Asic-sheet, and an` indicator having- `a fiiredvoperativeposition relatively to thetrackerboard, sa sheet havingav linewhich registers with the said indicator when the sheet is` in accuratealinement on the tracker, substantially as set forth.
